A former secretary to a Diet member was sentenced Tuesday to 30 months in prison for bribing the governor of Tokushima and two mayors in Ibaraki Prefecture.

The Tokyo District Court ruled that Mitsuro Ozaki, while a senior executive of Tokyo-based business consultant firm Gyosai Toshi Kaihatsu Kenkyusho (Gyosaiken), handed over some 13 million yen in connection with securing public works projects.

Presiding Judge Yoshinobu Iida said Ozaki, 57, abused the personal networks he had fostered while he was an aide to Lower House member Michihiko Kano.
